统一坐标系下二维气动方程组的Runge-Kutta间断Galerkin有限元方法
Runge-Kutta discontinuous Galerkin finite element method for two-dimensional gas dynamic equations in unified coordinate
摘要
Abstract
In this paper we develop the Runge-Kutta discontinuous Galerkin finite element method for two-dimensional compressible gas dynamic equations in unified coordinate.The equations for fluid dynamics and geometry conservation laws are solved simultaneously. All the calculations can be performed on the fixed meshes.The information about the grid velocities is not needed in calculation.Some numerical examples are given to evaluate the efficiency and the reliability of the scheme.The numerical results show that the algorithm works well.关键词
